Nanite - CPU performance with large open world, Many materials, even when nothing is visible.

The more detailed draw events should be available with r.RHISetGPUCaptureOptions 1. This will set a few cvars that emit a lot more data.

Alternatively, r.EmitMeshDrawEvents 1 will provide a breakdown. In 5.4, you will also need to set r.Nanite.ShowMeshDrawEvents 1 to get Nanite draw events.

Insights will need additional channels to see them too. I believe they reside in the RDG channel.

I hope that helps.

Best regards,

Chris
